Bats represent a unique group of mammals, characterised by different life strategies. They are the only mammals capable of active flight, which, combined with their almost exclusively nocturnal activity, has led to the evolution of specific adaptations. One of the most striking is echolocation, which enables them to orientate themselves perfectly in their surroundings in the dark. Bats are mainly native to the tropics, but have also colonised areas outside the tropics, which, has led to a complex phenological cycle with active phases and interruptions during hibernation, especially in temperate zones. In this diverse and species-rich group (almost 1,500 known species), there is a wide range of social organisation as well as feeding and roosting strategies. The textbook "Fundamentals of Chiropterology" brings the current state of knowledge about these extraordinary animals in eleven chapters and two appendices for the first time in the Slovak language.

Statistics is defined as a scientific discipline based on learning from data and on finding, controlling, and presenting uncertainty. In these university textbooks we present the history of statistics, basic concepts of statistical modeling, measurement of dependencies, regression models, analysis of variance. We describe simple sorting, multiple comparisons, assumptions of the ANOVA model, Kruskal-Wallis test. University textbooks are suitable for students of mathematics and computer science at the first and second level of universities. Study materials are also suitable for students of non-informatics disciplines with a view to improving their knowledge and practical experience in the fields of informatics and provide an opportunity for students to apply in IT companies in solving practical tasks.

The textbook "Bioenergetics" should serve as an introduction to the study of bioenergetics. This field of science is currently highly actual, as the results of the bioenergetics research in recent years clearly show that bioenergetics processes in living systems can "serve" not only to transformation of energy, but also affect the course of processes such as apoptosis, aging, origin and development of many diseases (especially neurodegenerative). These facts clearly indicate the need for the existence of quality teaching texts that would allow students to acquire the necessary information and knowledge in this scientific discipline in an acceptable way. For the above mentioned reasons, we decided to create these textbooks, which are in the form of ten chapters, which naturally and logically follow each other. One chapter basically presents one lecture within the course of Bioenergetics, which is realized at the Faculty of Science of the Pavel Jozef Šafárik University in Košice at the master's and doctoral degree of the study program "Biophysics". At the same time, these texts can also be used for teaching in the study subject Biochemistry, which is taught in the bachelor's and master's degree programs of the study programs "Biochemistry" resp. “Biophysics”. We would like to express our conviction that this textbook could in some way also help researchers working in the field of the energy transformation in biological organisms and the phenomena associated with this transformation. This textbook presents knowledge about the basic concepts of bioenergetics, the mechanisms of processes such as glycolysis and the Krebs cycle (in addition to a detailed and comprehensive description of these processes, there is also a general view of the interconnectedness of these processes and their incorporation into a compact view of the overall energy transformation in biological organisms), the structure and functionality of biological membranes (this area is necessary for a better understanding of the knowledge presented in the following chapters). In the following chapters, the textbook deals with the description of the structure and function of mitochondria, with great emphasis on the properties and mechanisms of functioning of the four complexes of the respiratory chain and ATP-synthase. These complexes create the basis for the existence of the "most important" process in bioenergetics, oxidative phosphorylation. In the final two chapters, the mechanisms of the processes that produce photosynthesis, its light and dark phases, are presented. There is presented relevant information about this "second" most important bioenergetics process taking place in many biological organisms and providing the possibility of transforming the energy of electromagnetic radiation into energy "hidden" in the chemical bonds of certain chemical molecules. We want to express our conviction that the textbooks "Bioenergetics" will be a good "helper and inspirer" for many students who want to learn as much as possible about the fascinating structures and mechanisms for energy transformation in living systems, without which it would not be possible existence of life as we know it.

Machine learning addresses the issues of how computer programs recognize complex patterns and make decisions based on data. In these university textbooks, we focus on theoretical knowledge in the field of machine learning in which we present the creation of concepts for objects, the preparation of concepts, hypotheses and the process of learning from examples. We describe Boolean formulas and their representations, probabilistic learning, linear and logistic regression, linear modeling and classification. Clustering and the Bayesian approach to machine learning conclude this publication. University textbooks are intended for students of master's degree programs in computer science.

The discovery of radioactivity at the turn of the 19th and 20th centuries stimulated the rapid development of nuclear sciences. At the interface between nuclear physics and chemistry, disciplines such as radiochemistry, radiation chemistry and nuclear chemistry were formed. The aim of the Nuclear Chemistry course which is taught at the PF UPJŠ is to provide basic knowledge, with an emphasis on the general value of the subject. It is important to make available the basics of various methods, techniques and their specifics in the application of nuclear phenomena in chemistry and related fields. Emphasis is also placed on the use of correct terminology, knowledge of the context of relationships and basic principles, supplemented by illustrative concrete cases. The choice of material is rather difficult, but we count on additional monographs and textbooks to fill in the gaps of these teaching texts.

Bibliographies provide basic scientific information, illustrate quality and intensity of research in a particular topic, area, or time, and thus help build a cultural-historical perspective of society’s appreciation of knowledge and education. Here we provide a bibliography of herpetological research in the region of Slovakia between the years 1791 and 2017. We collected 2,183 references authored by 1,453 different authors and covering all species of amphibians (18) and reptiles (13) occurring in Slovakia and, in addition, amphibian and reptile taxa occurring in 94 other countries. Most of the contributions were published in popular magazines and non-indexed journals, while only about 12% of all references represent scientific articles from journals indexed in relevant scientific databases. The extensiveness of study on amphibians and reptiles has varied among different periods within the selected time frame. However, an obvious intensification in the field of herpetology can be observed, especially during the second half of the 20th century. While there have only been few professionals specialized in herpetology, an important role in promoting the research and conservation of amphibians and reptiles in Slovakia has been played by non-governmental organizations and hobbyists. The most frequent type of herpetological data in the referenced literature comes from faunistic research, followed by conservation and general information on herpetofauna, with the majority of published articles in indexed journals coming from the fields of palaeontology, phylogeography, and population genetics. The presented bibliography is the first step towards building a solid base for future systematic herpetological research in the country and Central Europe.

Zborník abstraktov Študentskej vedeckej konferencie PF UPJŠ

Charakteristickou črtou vzdelávania na kvalitných vysokých školách, ku ktorým Prírodovedecká fakulta UPJŠ v Košiciach patrí, je úzke prepojenie vzdelávania a vedeckého výskumu. Poznatky a vedomosti z odboru štúdia získavajú študenti nielen teoretickým štúdiom jednotlivých disciplín, ale aj aktívnym zapojením sa do riešenia čiastkových vedeckých úloh v rámci výskumných tímov či už pri vypracovávaní záverečných prác alebo formou nástroja Študentských pomocných vedeckých síl (ŠPVS), ktorých činnosť sa na fakulte revitalizovala v roku 2015.

Študentská vedecká konferencia (ŠVK) je jedným z tradičných podujatí fakulty, ktoré je organizované počas Prírodovedeckých dní ako súčasť Sciencefestu. Svojou povahou prirodzene zapadá do spomínaného súkolia prepojenia vzdelávania a vedy a dlhodobo sa teší veľkej popularite a záujmu študentov. V roku 2016 na ŠVK vystúpilo 125 študentov Prírodovedeckej fakulty UPJŠ v Košiciach, v rámci 16 sekcií. Prehľad o zameraní a cieľoch študentských prác podáva tento zborník. Veríme, že bude inšpiráciou pre ďalších potenciálnych záujemcov o vystúpenie na ŠVK, ale bude zaujímavý aj pre širšiu verejnosť, ktorej môže podať doplnkový pohľad na činnosť fakulty.
